Robert Trivers argues that we deceive ourselves in order to better deceive others, in part because self-deception can reduce unconscious body signals of lying (von Hippel & Trivers, 2011).
On Wikipedia, self-deception is criticized for
...not being able to account for why evolutionary selection for lying would allow a body language that gives away lying to exist instead of simply selecting for lack of such signals. (Ekman, 2006; Damasio, Evans & Cruse, 2004) ...
What are the main arguments against this criticism?
